Bnnsrnme ATTACHMENT.

Application filed July 12,

T 0 all whom it may concern- Be it known that we, 'Ronnm Enrica GALLAGHER and REGINALD 'CHESNEY YOUNG, both of the city of Winnipeg, inthe Province of Manitoba, Canada, have invented certain new and useful Improvements in Bedspring Attachments, of which the following is the specification,

The invention relates to improvements in bed spring attachments and particularly to an attachment toa helical bed spring and an object of the invention is to provide an anti-sway device which will prevent thetop frame fromswinging laterally or endwise and which is also designed materially to assist the springs in carrying the weight and without losing any of the benefit of the springs.

A furtherobject of the invention is to construct the appliance in a simple, durable and inexpensive manner and so that it can be readily applied to the existing bed springs and such that the anti-sway device will permit the partial collapse of the spring for shipping or storing purposes.

lVith the abovemoreimportant objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularlydescribed and later pointed out in the appended claims, reference being had to the accompanying drawing in which z- Fig. 1 is a plan view of a bed spring, part being broken away.

Fig. 2 is a longitudinal sectional view at 2-2 Fig. 1 through the bed spring, the central part being removed.

Fig. 3 is a side view of the spring with. the central part removed and showing the top frame depressed.

Fig. 4- is an enlarged detailed cross sectional view through one corner'of the frame.

In the drawing like characters of reference indicate corresponding parts in the several figures.

The under frame 1 of the spring is of the ordinary construction presenting the customary side rails 2 and 3 which are connected by the usual head and foot rails 4i and 5 and by intermediate suitably spaced cross rails 6 similar to the head and foot rails. This under frame supports the spring from the bed frame which it fits.

Above the under frame is a substantially rectangular top frame 7 which is suitably Specification of Letters R atent. Pat t d J ly :18, 1922.

laced with lengthwise and crosswise extending wiresS. The helical springs 9 of the bed spring are located between the top and bottom frame and are suitably fastened to the cross rails and head and foot rails at their lower ends and are suitably tied by thewires 8 at their upper ends.

All the above parts are of ordinary construction and constitute What is customarily known as helical bed spring.

In such a spring .there is considerable lateral and endwise sway of'the top frame when the. same is use which acts in time to break down the springs, spoiling :their resiliency and the general shape of the bed spring;

Our invention, which is now described in detail and which comprises'the parts shortly to be described, is fitted to the bed spring at the corners between the top and bottom frames and as the corner fittings are all identical the description of one will suffice.

To the side rail ofthe underframe and adjacent the end thereof we connect pivotally at 10 a comparatively shortlever arm 11 which normally extends .upwardly in a slightly inclining position.

To the end of the top frame'we attach pivotally the outer end of a swinging bar 12, the inner end of the bar being pivotally attached at 13 to the upper end of the lever arm. This bar is offset at 14 to escape the corner spring. A coil tension spring 15 connects the upper portion of the lever arm with the outer end of the side rail, this spring acting to pull the lever arm towards the end of the spring frame.

At the upper end of the lever arm we locate a catch or stop 16 which is engaged in the normal position of the top frame with the top side of the bar 12, this stop limiting the down buckled position of the joint formed at the pivot pin 13. 7

When a bed spring is fitted with four of these devices, one at each corner, and with the devices at opposite ends opposed in position the springs 15 are normally under tension as are also the springs 9.

When. a weight is applied on the top frame the outer ends of the bars 12 swing down and the upper ends of the lever arms 11 swing inwardly, their in-swinging being resisted by the springs 15 which increase in tension, Any end sway of the top frame is positively prevented by the catches or stops 16 which positively prevent any down buckling of the joints.

It will be obvious from the construction of the anti-sway devices that the top frame can be collapsed considerably before the wire lacing thereof will interfere with the lever arms. This is an important advantage as one can compress and then tie the top frame to the bottom frame prior to storing or shipping and a number of springs will accordingly talre considerably less space.

In connection with the following claims, we wish it to be understood that where we speak of iii-swinging and out-swinging of the lever arm and bar we mean in-swinging to be a swing in a direction towards the central part of the bed spring and outswinging a swing in a direction towards the end of the bed spring.

lVhat we claim as our invention is:

1. The combination with a mattress, presenting upper and lower frames having cushioning springsinterposed therebetween, of means for preventing relative side sway of the said frames, said means ii'icluding levers pivoted to the side rails of the lower frame to swing only in the longitudinal direction of the rails, links connecting the free ends of the levers to the side rails of the upper frame, stops on the levers engageable with the links to limit upward swinging of the latter beyond a position substantially at right angles to the levers, and springs connected between the levers and the lower frame normally holding the levers inclined. toward the ends of the frames ant. tending to resist the swinging movement of the levers occasioned by depression of the upper frame.

2. In combination with a mattress, comprising upper and lower frames and cushioning springs interposed therebetween, levers pivoted to each side rail of the lower frame toward the ends of the latter, and swingable only in the longitudinal direction of the frame, links inclining inwardly from the opposite ends of the upper frame and connected at their inner ends to the free ends of said levers and contractable springs connected between the levers and the lower frame normally inclining the levers toward the outer ends of said frame.

The combination with a mattress comprising upper and lower frames and cushioning s rings interposed between said frames. or levers pivoted to each side rail of the lower frame at opposite ends of the latter. to swing only in the longitudinal direction of the frame, springs connected between said levers and portions of the frame lyinp; intermediate the levers and the ends of the frame, whereby the levers normally incline toward the ends of the frame, normally inclined links extending between the levers and the ends of the upper frame, projections carried by the levers engageable with the upper edges of the links to prevent upward swinging movement of the latter beyond a position substantially at right angles with the lever, whereby depression of the upper frame will tend to swing the levers against the resistance of the springs connect-ed thereto.
